Residual disease is the main, but not the only factor impacting satisfaction in psoriatic patients undergoing biological therapies.

Background: Despite advancements in psoriasis treatment, a gap remains in aligning patient satisfaction with clinical outcomes. Our study aimed to evaluate which clinical and psychological factors may impact treatment satisfaction in psoriatic patients undergoing long-term biological therapies.

Methods: We performed an observational, cross-sectional, single-center study involving adult patients with moderate-to-severe psoriasis treated with biologics for at least 12 months.

Graphene Thermal Infrared Emitters Integrated into Silicon Photonic Waveguides.

Cost-efficient and easily integrable broadband mid-infrared (mid-IR) sources would significantly enhance the application space of photonic integrated circuits (PICs). Thermal incandescent sources are superior to other common mid-IR emitters based on semiconductor materials in terms of PIC compatibility, manufacturing costs, and bandwidth. Ideal thermal emitters would radiate directly into the desired modes of the PIC waveguides via near-field coupling and would be stable at very high temperatures.

Evaluation of the Impact of Night Shift Work on Disease Severity in Psoriatic Patients: A Case-Control Study with Clinical, Hormonal, and Immunological Evaluation.

Introduction: Night shift work disrupts circadian rhythms and has been associated with immune system alterations and various health conditions. However, there is limited data regarding its impact on psoriasis. The aim of our study was to compare psoriasis severity and the hormonal and immunological profile in patients with a night shift work to those with a daytime occupation.

Clinical, epidemiological, and therapeutic hallmarks of pyoderma gangrenosum: a case series of 35 patients.

Background: Over the past few decades, advances in medical research and diagnostic tools have shed light on some aspects of pyoderma gangrenosum (PG). Nevertheless, the multifactorial etiology, pathogenesis, and optimal management strategies for PG need to be further investigated. To address these knowledge gaps and contribute to a better understanding of this complex dermatological disorder, we collected epidemiological, clinical, and therapeutic aspects of a case series of PG patients occurring in our department over the past 10 years.

Low grade of satisfaction related to the use of current systemic therapies among pustular psoriasis patients: a therapeutic unmet need to be fulfilled.

Introduction: Pustular psoriasis is considered a separate entity from plaque psoriasis and can be categorized as generalized pustular psoriasis (GPP), acrodermatitis continua of Hallopeau, or palmoplantar pustulosis (PPP). Current guidelines mostly include treatment options that have not been specifically developed for the treatment of pustular psoriasis. The majority of them does not have indication for the treatment of pustular psoriasis.

Facial Papulopustular Eruption during the COVID-19 Pandemic in Patients Treated with EGFR Inhibitors.

Papulopustular rash (PPR) is the most frequent cutaneous adverse event during treatment with epidermal growth factor receptor inhibitors (EGFRis). Although often mild in severity, it can impair patients' quality of life and may also be a reason for discontinuing or changing the dose of the antineoplastic treatment. During COVID-19 pandemics, the use of surgical masks drastically increased and it had an impact on the face skin microenvironment, favoring the worsening of dermatological pathologies.

Drug survival of methotrexate and predictor factors for discontinuation in psoriasis.

Background: Methotrexate (MTX) is a systemic therapy largely used for moderate-severe psoriasis. There is a lack of data on its use in daily practice and particularly on its long-term effectiveness and survival in psoriasis.

Methods: We performed a single-centered, retrospective, observational study to evaluate the drug survival of MTX in patients with psoriasis, treated in monotherapy with MTX between March 2015 and March 2022.

Cold-Induced Urticaria in Children.

The exposure to cold can induce the development of wheals and angioedema in a group of susceptible individuals: this phenomenon is largely known as cold-induced urticaria. The pathogenesis of cold-induced urticaria is not yet understood, although both autoallergens and immunoglobulin (Ig)E-mediated autoimmunity are presumed to be involved. Flares of cold-induced urticaria might depend on the release of histamine and other pro-inflammatory mediators, such as Interleukin (IL)-1, which is the predominating stakeholder of cryopyrin-associated periodic syndrome, a genetic disease characterized by cold-induced skin manifestations, including urticaria-like rashes.

GaInP nanowire arrays for color conversion applications.

Color conversion by (tapered) nanowire arrays fabricated in GaInP with bandgap emission in the red spectral region are investigated with blue and green source light LEDs in perspective. GaInP nano- and microstructures, fabricated using top-down pattern transfer methods, are derived from epitaxial GaInP/GaAs stacks with pre-determined layer thicknesses. Substrate-free GaInP micro- and nanostructures obtained by selectively etching the GaAs sacrificial layers are then embedded in a transparent film to generate stand-alone color converting films for spectrophotometry and photoluminescence experiments.

Gallium indium phosphide microstructures with suppressed photoluminescence for applications in nonlinear optics.

Gallium indium phosphide (GaInP), lattice matched to gallium arsenide, shows remarkable second-order nonlinear properties, as well as strong photoluminescence (PL) due to its direct band gap. By measuring the second-harmonic generation from the GaInP microwaveguide (0.2×11×1300  μm) before and after stimulating intrinsic photobleaching, we demonstrate that the PL could be strongly suppressed (-34  dB), leaving the nonlinear properties unchanged, making it suitable for low-noise applications.

In situ nondestructive identification of natural dyes in ancient textiles by reflection fourier transform mid-infrared (FT-MIR) spectroscopy.

Silk embroideries and cotton grounds of ancient Caucasian (Kaitag) textiles were analyzed in situ by a portable Fourier transform infrared (FT-IR) spectrometer equipped with a reflection module. Differently colored areas were analyzed for the purpose of identifying the dyes fixed on the fibers. The spectra so obtained were elaborated by calculating the corresponding second derivative, and a library search was then performed using a database including the second derivative spectra of a large range of historical dyes and the corresponding undyed fibers.

[Congenital valvular heart disease with high familial penetrance].

Bicuspid valve aortic (BVA) is one of the most common congenital malformations. Only 20% of patients preserves a normal valve function throughout life. There are sporadic and familial forms, the latter to autosomal dominant.

Identification of natural dyes on laboratory-dyed wool and ancient wool, silk, and cotton fibers using attenuated total reflection (ATR) Fourier transform infrared (FT-IR) spectroscopy and Fourier transform Raman spectroscopy.

Attenuated total reflection (ATR) infrared and Fourier transform (FT) Raman spectra were obtained from wool threads dyed in the laboratory with natural dyes used in antiquity, following a procedure similar to ancient methods for dyeing wool. The ATR spectra were primarily dominated by the signals of the wool, making it difficult to identify the dye on the fibers only by visual inspection of the infrared spectrum. However, the Raman spectra showed more significant characteristics attributable to the dyes as previously studied in the literature on modern synthetic dyes.
